I no longer believe the ads have anything to do with Android 8, as I'm seeing the same thing on another phone running Android 6. Recently I was working in my garage, expecting a phone call. The phone was left on a workbench several feet away. When the phone rang, I rushed over to pick it up, only to be greeted with a full screen ad for Facebook. When I figured out how to clear this ad, I was immediately greeted with another ad, this time for NordVPN, which I also had to clear. The point is, I almost missed the call. My feeling is that these ads come from Google, since it makes no difference what app, if any, that I'm running, and the ads are not always for the same product. It just seems as though Android phones are becoming more a vehicle to push advertising, and less useful as a phone. Also,, why is it I purchase a phone with a certain amount of internal memory, only to find that I can't use at least a third of that memory because of included apps I'll never use, e.g. Facebook? I'd like to root my phone, but there seems to be no way to do that on my LG product. I'm beginning to think I might have to start considering Apple for my phone needs.
